Default Automatic RF noise cancellation and audio noise measurement
Does anyone know of circuits that measure audio noise?

Sure, Short out your rf input to the audio amp, and measure the noise. If you
have a noisy output after you short the input, then you have a noisy amp. If
you have a noisy audio amp, then you need another design.
